Given below are two statements:

Statement I: RSPM are those suspended particulate matters (SPM) whose aerodynamic diameter is more than 10 micron. Statement II: Fine particles are those SPM whose aerodynamic diameter is less than 2.5 micron.

In the light of the above statements, choose the most appropriate answer from the options given below:

  1. A.

    Both Statement I and Statement II are correct

  2. B.

    Both Statement I and Statement II are incorrect

Attempted by 10 students.

Show answer & explanation

Correct answer: D

RSPM refers to respirable suspended particulate matter with diameter less than 10 microns, making Statement I incorrect. Fine particles or PM2.5 have diameter less than 2.5 microns, making Statement II correct. Thus, Option 3 is the appropriate answer.
